YES! Make sure the Bluetooth is turned on, on your iPhone. Make sure the headphones are turned off, then hold the power button (middle one) on the headphones till you hear them say they are searching for a device (you will hear them say 'power on' first just keep holding the button)! Mine connected with no problem on my iPhone 6! If you have any issues look up the official instructions for the headphones, they have the detailed instructions.

I just bought an iPhone 6 and guess what? When I turned on bluetooth on iPhone 6, it was unable to detect my JayBird BlueBuds X. My BlueBuds can still be detected and paired with a Samsung S3, so I'm pretty sure it is functional.
Anyone else encountered the same issue?

Yes, turn Bluetooth on your iPhone 6, turn on your BlueBuds X then press volume up and down at the same time on your BlueBuds X. After that , in Settings, Bluetooth on iPhone 6, BlueBuds X appeared under MY DEVICES. Go and click BlueBuds X. The lady voice on your BlueBuds X will confirm that they are paired. That is how I was able to pair them.

Bluetooth Headphones like these use an A2DP protocol to send sound to your device. Bluetooth 4.0 is used to connect devices such as heart monitors and pedometers. They don't interfere with each other so you'll be able to use both types at once without a problem.

I have connected the Bluebuds X with the Iphone 6 plus (with iOS 8.0.2). While I can hear the music and use the volume up/down key to control the volume or tracks, I cannot pick up incoming call. I have followed the advice from the JayBIrd Support Team to reset the earphone but the problem cannot be solved. Any advice?

Can anyone explain exactly how the Bluebuds X switch between two (already paired) devices? Say I'm currently listening to a podcast on my iPhone but now want to watch a video on my iPad. On my current BT headphones (Sony MW600) the switch has to be handled by the headset, not from the iOS devices. Which means fiddling around with a (very clunky) interface on the headset.

How exactly do you manage the transition with the Bluebuds? Do you simply toggle off Bluetooth on the iPhone (using the handy toggle in Control Centre, once iOS7 is available!) and then immediately find that you can connect the iPad to the Bluebuds via the Airplay button in the multitasking drawer (or alternatively from the Bluetooth menu in Settings)?

While you are connected to the iPhone, all you have to do is go to your second device (iPad) and select BlueBudsX on the Bluetooth settings. BlueBuds X voice prompts will say "connection switched" and you can start using the iPad immediately. You don't need to do anything on the iPhone or BlueBuds X if they are already paired to both devices. Does that make sense?
